Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

full passthrough of 12th gen Iris Xe seems working now
OVMF: edk2-stable202302 patched with ACRN patch (https://github.com/johnmave126/edk2/tree/intel-gop-patch, also see https://github.com/Kethen/edk2)

Intel Iris Xe (Tiger Lake) passthrough (GVT-D)
Can't use Kethen/edk2 because my BIOS update has no IntelGopDriver (it doesn't even have IntelGopVbt but rather IntelGopVbt2)

UEFI + Intel GVT-D + Display Output + HDR (Kethen/edk2) - Some tips and HDR questions
I wanted to share some tips on how to get this working. The repo below allows you to build an OVMF bios which allows a UEFI virtual machine to work with display output when using Intel integrated graphics: https://github.com/Kethen/edk2

tiger lake Iris Xe single GPU passthrough
I used my laptop BIOS file from which I extracted the efi IntelGopDriver and vbt files (note that it seems to have two vbt in BIOS file), I used the same one I found in "/sys/kernel/debug/dri/0/i915_vbt", then I recompiled OVMF with this files using https://github.com/Kethen/edk2.

iGPU passthrough on server - Is it possible?
For Haswell, IGD/GVT-d is possible. Use -machine pc (i440fx) + Kethen/edk2 + vbios_gvt_uefi.rom + x-igd-gms=2. You might be able to get -machine q35 + to work but without boot display. Look for a single GPU passthrough script.

Full passthrough / GVT-d of 11th gen iGPU (Rocket Lake) to Windows 10 guest - logging my attempt.
Try Kethen/edk2.

dual boot or virtual machine?
I was able to get laptop display output to work via i440fx (machine) + Kethen/edk2's OVMF (UEFI) + vbios_gvt_uefi.rom (romfile) + x-igd-gms=2 (2 * 32MB graphics memory). I think you might need to also use CPU host passthrough but I'm not sure.
- Is anyone had a success to passthrough Intel iGPU (Skylake) using q35 emulated chipset?

Single GPU passthrough with intel
I got i440fx with boot display + OS display to work using Kethen's edk2 + vbios_gvt_uefi.rom

GVM: A GPU Virtual Machine for Iommu-Capable Computers
Intel has already confirmed that GVT-g is essentially dead and not supported on their Iris/Xe or anything newer graphics.. We can also confirm this via their own drivers source..

Laptop GPU for Host use in PCI OVMF pass thru? + confusion re using iGPU
On Intel iGPUs, there are two methods: GVT-g and GVT-d. GVT-g is basically creating virtual instances of the iGPU for use in VMs, while GVT-d is passing through an entire iGPU to the guest in the same way you would do with a normal GPU.

list of gvt-d supported cpu? thx

Kholia/OS X-KVM: Run macOS on QEMU/KVM
Not really pass through, no. If CONFIG_DRM_I915_GVT is enabled in your kernel, you can use Intel's graphics virtualization system... basically a virtio style virtual device that shares the GPU between VM and host. IMO this is way more convenient than real passthrough, where the device is only available either to the VM or the host. The downside is that you don't get full performance in the VM.
"Intel GVT-g is a full GPU virtualization solution with mediated pass-through (VFIO mediated device framework based), starting from 5th generation Intel Core(TM) processors with Intel Graphics processors. GVT-g supports both Xen and KVM (a.k.a XenGT & a.k.a KVMGT). A virtual GPU instance is maintained for each VM, with part of performance critical resources directly assigned. The capability of running native graphics driver inside a VM, without hypervisor intervention in performance critical paths, achieves a good balance among performance, feature, and sharing capability."

Full passthrough / GVT-d of 11th gen iGPU (Rocket Lake) to Windows 10 guest - logging my attempt.
Wait a minute. GVT-g with 11th gen iGPUs upwards does work in linux guest? Are you sure about that? See this github issue for reference.

Show HN: VGPU and SR-IOV on Consumer GPUs
To be clear, I never said it was dead, only a dead end.
As for GVT-g and Xe, according to a post in this[0] issue by one of the Intel devs, Rocket Lake (Xe) is not getting support and only does GVT-d.
Also in the same issue, someone pointed out that Intel themselves have states as much here[1].
I hope I am proven wrong in the end and GVT-g comes to then entire Xe and ARC lineup. Intel's communication on this matter has been...lacking.

GVT-D setup
After days of trial and error, I could not get it to work, maybe one of you knows it. Currently, I try to setup GVT-d with KVM on my Dell XPS 13 2 in 1 7390, which has a i7-1065G7. AFAIK GVT-g is not supported, so I gave GVT-d a chance. The virtual machine is booting without any errors, but the display stays black. I only found this guide, but couldn't get it to work...
